I bought this at a home improvement store. I bought it for practicing cycling, but my child disliked it and wouldn't wear it, so it was never used outdoors. It's an unused item that was only tried on, but it has been stored at home for about a year, so please refrain from purchasing if you are looking for perfection or are sensitive.
